Soylent Green, without a doubt. Long list of stars, but absolutely the worst EVER, IMO.
I will have to personally disagree with you here. Not that it wasn't bad - it was. Certainly it is on a list of duds. What I think saved it was Charlton Heston. Why a major star like him, would take such a movie is beyond me. Maybe he really needed the money. :scratch2:
I think with Soylent Green it was a science-fiction film that did not anticipate changes of technology, especially in agriculture. It is my understanding that crop yields today are 35-40% higher per acre than in the late 1960s for example. Furthermore, it followed a whole mold of these apocalyptic science-fiction disaster movies....
Planet of the Apes (1968) and its rather forgettable squeals through 1973. Omega Man (1970), Earth II (1974), Phase IV (1973), Andromeda Strain (1971), Silent Running (1972), Solaris (CCCP - 1972), Damnation Ally (1976), and yes in the late 1970s to mid 1980s, the Mad Max series (Mad Max (1979), Road Warrior (1982), Mad Max Beyond Thunderdome (1985))... And many others...
The theme is always the same, the quality of the product is vastly different. The Mad Max series was very good (Road Warrior is my favorite
), as was Andromeda Strain, and Silent Running is an absolute classic....
In terms of viewpoints, development, and story, I would say that Avatar was much worse than Soylent Green in every aspect. The only thing it had going for were the incredible special effects which were undreamed of when Soylent Green was made (on a very limited budget I believe). :yes:
